Force Measuring Apparatus of Ground Anchor and Tensile Force Measuring Method of Ground Anchor Using the Same
According to the present invention, provided is an anchor tensile force measuring apparatus mounted on an excavator. The anchor tensile force measuring apparatus comprises: an elastic wave transmission medium mounted on one side of a fixing structure for fixing and fixing the end of a strand that is penetrated underground, emitting an elastic wave to the other side of the fixing structure, and receiving the elastic wave reflected from the other side of the fixing structure; and a calculating unit for receiving the transmission speed data of the elastic wave measured through the elastic wave transmission medium and deriving the tensile force of an anchor based on the difference in the elastic wave transmission speed depending on the restraining pressure.
본 발명에 따른 굴삭기에 장착되는 앵커 인장력 측정장치는, 지중에 관입 설치되는 강연선의 단부를 고정 정착시키는 정착 구조체의 일측면에 장착되어, 탄성파를 상기 정착 구조체의 타측면 측으로 방출하며, 상기 정착 구조체의 타측면에서 반사된 탄성파를 수신하는 탄성파 전달 매체 및 상기 탄성파 전달 매체를 통해 측정된 탄성파의 전달 속도 데이터를 전송받아, 구속 압력에 따라 달라지는 탄성파 전달 속도 차이를 기반으로 앵커의 인장력을 도출하는 연산부를 포함한다.
